RUBBER TIRE.

SPECIFICATION formiug'part of Letters Patent No. 782,379, dated. February 14., 19,05.

Application filed July 28, 1904. Serial No. 218,470.

To all whom it may concern:

Be it known that I, CLARENCE H. BRYAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Rubber Tires, of which the following is a specification.

My invention relates to elastic tires for vehicle-wheels and the like, and has for its object to provide new and improved construcl tions for such devices.

My invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side view of a vehicle wheel with part ofthe liange device broken away. Fig. Qisasectional view of the tire and felly on a radial line of the wheel. Fig. 3 is a side view of a portion of the tire shown in Fig. 2. Fig. 4 is a sectional view showinga modified form of the tire. Fig. 5 is asection through another modified form of tire. Fig. 6 is a side view of a portion of the tire shown in Fig. 4.

Like parts are indicated by like letters in all the drawings.

A is the hub of the wheel; BB, the spokes; C, the felly, which may be made of wood or any suitable material and is preferably provided with a metal hoop or shoe C and annular washers C2 C2, composed of leather or other suitable tough material.

D represents the tire, made of rubber or other resilient material and whichis preferably of the dimensions shown-that is, about the width of the wheel-felly, but with its radial thickness considerably greater. The tire is given a somewhat fiat seat upon the felly and is protected at this place by a covering of tough fabric, as shown in D. The tire D is held to its position upon the rim and prevented from bending laterally by a movable cage-like fastening and guiding device. To this end the tire is pierced at intervals approximately midway between its seating portion and the tread by a series of perforations D2, extending from side to side. These perforations are somewhat enlarged or elongated radially for the purpose lthat will appear later. On each side of the wheel I provide the annular lianges E E, which extend along the side of the tire and of the felly, the latter vention.

being protected from wear by the washers C2 C2. These iianges are held in proper relation by the sleeves F, which pass through the perforations D2 and are secured by bolts F', passing through the sleeves, and the nuts F2. The sleeves hold the anges approximately parallel andV slightly removed from the side of the tire. In order to prevent wear, the perforations are lined with a tough fabric, and the sides of the tire, near the perforations, are covered with a like material, as shown at D5. In order to provide for the compression of the tire, the mass of the tire is reduced within the liange devices. This may be done by making annular grooves in the sides of tire, as shown at D3 D3 in Figs. 2 and 3. However, the purpose being to reduce the mass of the tire which is within the holding device so that the tire may be made more resilient and accommodated to act within the holding device, this purpose is susceptible of accomplishment in more than one way. For example, as shown in Figs. 4 and 6, the tire may be perforated with a series of transverse holes D, extending from side to side of the tire, or, as shown in Fig. 5, it may be provided with one or more annular channels D7, extendinglongitudinally. In such cases the tire need not have the grooves or depressions on the sides, as shown in Figs. 2 and 3. Obviously this end could be accomplished innumerous dierent ways, and therefore I do not limit myself to the particular forms of tire shown. To strengthen the tire, in the form of tires in Figs. 2 and 3 at the places where it is pierced for the bolts I preferably make it with the lugs D4. rlhe bolt-holes are made oval in shape and approximately twice as long as they are wide. However, this shape and these dimensions are not material to my in- As an aid to holding' the tire in position, the seating part of the tire may be made to extend beyond the felly, as shown in Figs. 2 and 5, so that it will contact with the ianges E E.

In the foregoing description I- have described three particular forms of my invention; but it is obvious that they might be modified in many respects without departing from the broad spirit of my invention. The

tire might be given a considerably dierent IOO shape from those shown and might be made of any suitable material and either in one piece or in sections. The dimensions, forms, and constructions might clearly be considerably changed without departure from the intent and purpose of my device, and therefore I do not limit myself to the particulars shown.

` its entire thickness.

The use and operation of myinvention will perhaps have been sufficiently clear from the foregoing. Suflice it to say that by the use of this device I am able to have a tire which is very resilient, the whole mass of the rubber or other material being capable of compression under the load. This follows from the fact that the tire is not conned in an immovable groove, but is free to move throughout rIhe elongation of the bolt-holes permits play between the tire and the cage-like holding device, with the result of giving added resiliency and also saving wear and tear upon the tire at the place where it is so connected. The tire when compressed will first be crushed down upon the sleeves and then with furtherpressure will force the holding device inwardly. I find that thisl results in a high degree of elasticity and great durability.

I claim- 1. The combination of a vehicle-wheel with an elastic tire having apertures therein and means to connect the tire with the rim comprising members movable withrespect to the rim and adapted to extend into the apertures, such apertures being of suiicient size to permit play between such members and the tire, when the tire is in use.

2. The combinationof a vehicle-Wheel with a tire of resilient material, radially-elongated apertures through the tire, and a device connecting the tire to the rim, comprising members passing through such apertures and move able with respect to the wheel.

3. The combination of a vehicle-wheel with an elastic tire, perforations through the tire, annular guide-iianges, sleeves passing through the perforations and adapted to hold the lianges in proper relation to the rim and the tire and bolts rigidly securing together the lianges and the sleeves.

4. The combination of a vehicle-wheel with a tire of considerable radial thickness in proportion to its lateral thickness, radially-enlarged perforations approximately midway between the tread and the seating portion of the tire, a connecting device comprising annular flanges adapted to make a sliding connection with the wheel, bolts passing through such perforations and secured to the anges and sleeves surrounding the bolts.

5. The combination of a vehicle-wheel with a tire of considerable radial thickness in proportion to its lateral thickness, radially-enlarged perforations approximately midway between the tread and the seating portion of the tire, a connecting device comprising annular ianges adapted to make a sliding connection with the wheel, bolts passing through such perforations and secured to the flanges and sleeves surrounding the bolts, such tire provided with a relatively fiat bearing on the wheel-rim and adapted to contact with the anges at this place.

6. The combination of a vehicle-wheel with a tire of considerable radial thickness in proportion to its lateral thickness, radially-enlarged perforations approximately midway between 4the tread and the seating portion of the tire, aconnecting device comprising annular flanges adapted to make a sliding connection with the wheel, bolts passing through such perforations and secured to the fianges and sleeves surrounding the bolts, such tire provided with a covering of tough fabric on the portion bearing upon the rim.

7 The combination of a vehicle-wheel with an elastic tire and a guiding device to hold the tire in place on the rim of the wheel, such device movable with respect to both the tire and the Wheel.

8. The combination of a vehicle-wheel with an ela'stic tire and a guiding device movable with respect to the wheel to hold the tire in place on the rim of the wheel, the portion of the tire Within such guiding device being reduced in volume.

9. The combination of a vehicle-wheel with an elastic tire and a movable guiding device to hold 'the tire on the rim of the Wheel, the

portion of the tire within such device being the guiding device being' of a size and shape to permit the displacement of the material of the tire under the resilient action thereof.
